KC1 keychain light is available now

Thanks lightdecay for your quick answer.

I wish they were, as an option which I would be happy to pay for. I didn’t choose Al for its lower price, but for being more lightweight than the other versions.

I always thought this myself. I would never choose any of those materials over aluminum due to weight, but I would gladly pay more for the lighted switch option also.

I’d say if price is not a “concern”, the cu+ti weight must be close to the AL… maybe? Albeit a different balance of weight, titanium is a decent degree lighter then AL, I believe. I’m sure someone who have both can verify this for us?

Ti is 2/3 more dense than Al.

Oh how I wish the Cu was coated to keep that shiny finish.

Yes but think of the joy you’ll have every time you re polish it :stuck_out_tongue:

good to know. thank you

lol

don’t tempt me, this is my excuse for not ordering one! :person_facepalming:

I emailed Hank and asked if a backlit switch would be an option on the standard D4V2 and his reply was that there were no plans to do it. That was a few months ago though. I’m holding out and not ordering anything else, because every time that I do the upgrades are always out minutes after I get my shipping notice.

Emisar D4V2 Sand XPL-HI V2 5D 4000K arrived! :beer:

Thats a beaut!

I’ve just emailed him with the same request, wait and see…

I don’t have any plans to order another D4v2.

… but if they add the backlit switch to the aluminum version I would.

I’m about to the point where I’m going to order every light Hank sells with every emitter he has. I love my D4V2 and my 2000k KR4. I should do the math on that :slight_smile:

Is thermal performance any better vs aluminum

Hank told me lighted switch on aluminum was a no go when I asked him last week. Really wish he would do it. Didn’t stop me from ordering another D4v2 with my K1 though…

Short answer - Yes.

Not positive on that.

I don’t have a full-copper D4V2, but I do have full-copper for a number of other lights.

Copper conducts heat so well the body tube of the light where your hand sits can get burning hot far faster than an aluminum tube.

The result is the electronics might be protected… but you may need gloves (or an oven mitt) to actually hold the light.

I noticed my fw3 copper got hot very quickly. My brass d4v2 does too, but with different emitters in my 3 lights of comparison it’s difficult to tell why or how much faster.

Ya my KR4 gets pretty hot cause I use it as my desk light. I try to keep the brightness at a level that is sufficient but doesn’t make the light get warm. Sometimes I neglect to do that and it gets hot. Not sure if that affects the life of the light but if so it just gives me a good excuse to buy another (:

I’d love a D4SV2 in 2000K.
